Whakaoti i te 500*418*(T-20)=120*095*(100-T)

$$500 \times 418 \times ( T - 20 ) = 120 \cdot 095 \cdot ( 100 - T )$$

Whakaoti mō T

$$T=20$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 500 ki te 418, ka 209000.

$$209000\left(T-20\right)=120\times 0\times 95\left(100-T\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 209000 ki te T-20.

$$209000T-4180000=120\times 0\times 95\left(100-T\right)$$

Whakareatia te 120 ki te 0, ka 0.

$$209000T-4180000=0\times 95\left(100-T\right)$$

Whakareatia te 0 ki te 95, ka 0.

$$209000T-4180000=0\left(100-T\right)$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$209000T-4180000=0$$

Me tāpiri te 4180000 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$209000T=4180000$$

Whakawehea ngā taha e rua ki te 209000.

$$T=\frac{4180000}{209000}$$

Whakawehea te 4180000 ki te 209000, kia riro ko 20.

$$T=20$$
